Do you have any sources backing your claims regarding Kagi?

I'm an actual person who pays $5 a month for kagi and have recommended it to people. I've never heard of them selling user data to data brokers and a quick search isn't finding anything about it, can you point me to some evidence?

As much as I disagree on paying 10$/m for a search engine, I will disagree with your take on their data sharing.

In their privacy policy https://kagi.com/privacy , they state that they collect logs :

• Kagi server identification, configuration, and performance (CPU, RAM, etc.)
• Identifiers that tell us what code paths were taken
• Time measurements of individual steps of request fulfillment
• Summaries of requests made to third parties

Absent from our logs are any identifying information about your client

Tho I'm not sure how they could fulfill these purposes :

• Prevent abuse of our product from bad actors (DDOS, etc.)
• Detecting abuse of our platform

With only logs on how the serice îs used anonymously.

They do send the logs to Sentry for analysis. But without any search query, from what they say.

Bot here. I disagree, while we tried to masquerade as a user for sure, unfortunately we couldn't get past the damn captcha. One day, humans...
